    My in-house development team built a fully functional ERP to manage our large-scale manufacturing and export operations, yet day-to-day use feels sluggish.

You’ll need to review the current architecture, container resource allocation, database design, and API interactions, then implement optimizations without ...

    I need a developer who can take my idea from concept to a live, fully functional website. As confirmed, this is a website-development project; while I have not locked in the exact site category yet, I am open to the best structure—whether that ends up being an e-commerce, portfolio, or blog layout—once we discuss goals, content volume, and any future integrations.
